...Checkpoint: Week 1 Day 5 OSI Model When we breakdown the OSI model you will see that in the seven layers of the design, a decision is made in the third layer, which WAN protocols operate on is known as the network layer. This layer carries out regular tasks such as pinpointing routings diagrams and end to end addressing. Some layers associate a unit also known as a brouter that works like a bridge and a router. Now on layers two thru four routers and switches work on these layers which are commonly known as the data link layer and the transport layer. As stated earlier on the network layer, which is layer two on the OSI model, is where the routing and addressing are carried out. In the OSI model during the transport layer is where we see the mistake handling and the flow control at work. Finally, synchronizations and assemblies are finished on the fourth layer of the OSI model. Configured of various parts every layer conducts a unique role inside the network. Additionally, each layer incorporates everything to the data which is then transmitted point to point. Protocols at work during this time are known as the frame relay protocol, HDLC, and PPP. The protocol that works as a data link layer is known as the frame relay protocol in the OSI model. The HDLC means high level data link in the model, and the PPP is an additional protocol which works on different layers of the OSI...

What would happen if wireless devices were not governed by the WIFI Alliance and each vendor had its own standards and protocol? What impact would this have on your personal life or business communications? If the governed was not WIFI Alliance then each company will lose it customers because if you set a standard in just buying your product then you’re not going to go any farther than just a couple of months in selling them. This will lose interest in buying the product because then I would not know if it is safe or not. Lab 3.1 Review 1 1. Why would a three- layer model of communication that has the layers physical, network, and application be insufficient to adequately describe network communication? 2. What is the history of the OSI reference model? How did it come about and why was it created? ` 3. What is the history of the TCP/ IP model? Why was it created? TCP/IP has two different names that come from. These key protocols two are usually considered the most important. The internet Protocol is the primary OSI network layer protocol that provides addressing, Datagram routing and other functions in a network. They were developed together with TCP/IP providing the mechanism for implanting the internet.

...Week Four Individual Assignment Kevin M. Gattas University of Phoenix IS Concepts Richard Bohn Purpose The importance of the OSI (open systems interconnection) model is for networks to communicate within the system. It is a system formed to allow a network administrator to perform trouble shooting in a way that is logical and step by step within the OSI model Scope The purpose of this essay is to break down the seven layers of the OSI model. The seven layer model defines a standard by which to computer share data over a network space starting with application layer. It will break each modeling section to lay out a more detailed explanation of how each layer is operated and how they all work together. Also, it will discuss which level this packet filtering routers and firewalls reside at, how packet filtering routers and firewalls protect the network and the concepts of cryptography. The seven layers of the OSI model are: 1. Physical layer 2. Data link layer 3. Network layer 4. Transport layer 5. Session layer 6. Presentation layer 7. Application layer Application Layer (Layer 7) The application layer is the most directly related to computer user because it is the top of the layer hierarchy. This layer provides several application services such as file transfer, resource allocation and whether the identification and verification of the computer is available. This layer is most familiar to us because it is what we commonly...

Describe the three modes of communication available on a network. (Minimum word count: 60) Simplex Data travels in only one direction, similar to a public address (PA) system. Half-duplex Data travels in two directions, but in only one direction at a time, similar to a walkie-talkie. Traditional shared Ethernet uses half-duplex transmissions. Full-duplex Data travels in two directions simultaneously, similar to a phone conversation. Full-duplex Ethernet (or switched Ethernet) supports full- duplex transmissions in a switched environment. 2. List the seven layers of the OSI model, including both layer number and name for each.

...Week 3 Team Assignment NTC/362 November 24, 2014 OSI Model The Open Systems Interconnection (OSI) has been a reference for model network protocols since the mid-1990s. The OSI is formally known as the Open Systems Interconnection (OSI) model ISO/IEC 7498-1. The International Organization for Standardization (ISO), is a global standards-settings group that is comprised of members from various national standards groups. International Electrotechnical Commission (IEC) is another global standards-settings group; however, it focuses on electrical, electronic, and related technologies. (Foundational Focus: OSI Model-Breaking Down the Seven Layers, 2013) The OSI model is comprised of seven layers, with layer one positioned at the bottom of the layer stack and layer seven at the top. The layers have assigned names as well as number references. Layer 7, the application layer, is the interface between the protocol stack and application software. The software might be client or utilities or server services. It is the ability of software to communicate with the standardized interface of application layer protocols that makes network communications possible. Layer 6, the presentation layer, establishes the context between disparate application layer protocols. Effectively, the presentation layer adjusts syntax, semantics, data types, data formats, etc. This layer ensures that data sent by the application is compatible with the lower layers of network communication and that data...

...Lab 5 Instructions Packet Tracer: Use of the TCP/IP Protocols and the OSI Model [Adapted from Cisco Networking Academy Network Fundamentals] Background: In Packet Tracer simulation mode, you may view detailed information about packets and how they are processed by networking devices. Common TCP/IP protocols are modeled in Packet Tracer, including DNS, HTTP, TFTP, DHCP, Telnet, TCP, UDP, ICMP, and IP. Packet Tracer uses a representation of the OSI model to display how these protocols are used by networking devices in creating and processing packets. The term “protocol data unit,” or PDU, is a generic description of what are known as segments at the transport layer, packets at the network layer, and frames at the data link layer. Help Files and Tutorials: From the pull down menu, choose Help->Contents. A web page will open. From the left frame, choose Operating Modes->Simulation Mode. If you are not already familiar with it, read about simulation mode. Realtime and Simulation Modes: In the far lower right of the PT interface is the toggle between Realtime and Simulation mode. PT always starts in Realtime mode, in which networking protocols operate with realistic timings. However, a powerful feature of Packet Tracer allows the user to "stop time" by switching to Simulation mode. In Simulation mode, packets are displayed as animated envelopes, time is event driven, and the user can step through networking events. To switch from Realtime mode to Simulation mode, click...
